Abstract: An apparatus for finely actuating a glass electrode or the like tool includes a movable portion adapted to be vertically displaced with the aid of a vertical actuating mechanism. A Y-coordinate slider is mounted on the movable portion to slide in the Y-coordinate direction and a X-cordinate slider is in turn mounted on the Y-coordinate slider to slide in the X-coordinate direction. A Y-coordinate thrusting rod is provided in the movable portion to thrust a Y-coordinate lever rod disposed between the Y-coordinate thrusting rod and the Y-coordinate slider, while a X-coordinate thrusting rod is likewise provided in the movable portion to thrust a X-coordinate lever rod disposed between the X-coordinate thrusting rod and the Y-coordinate slider. This enables a lever ratio to be reduced to a fraction of the ratio. Two return springs are provided so as to allow both the Y-coordinate slider and X-coordinate slider to resume their original position. One of them is resiliently bridged between the movable portion and the Y-coordinate slider and the other one is resiliently bridged between the Y-coordinate slider and the X-coordinate slider.

Abstract: 546,248. Valve circuits for wireless reception. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 2, 1941, No. 91. Convention date, Jan. 2, 1940. [Class 40 (v)] In a superheterodyne circuit, tracking is improved in a pair of unicontrolled permeability tuned inductances by providing a condenser in shunt with a portion of the oscillator coil. Ir the Figure, a mixer 10 is fed by an aerial coil 5 tuned by a movable coi 7 and an oscillator core 6 tuned by a movable core 8, the cores 7 and 8 being uni-controlled In one frequency range the coil 5 is connectec to the aerial 22 by means of a ganged pai of switches 23, 24 through a series con denser 21 and shunt con denser 20, while for a second frequency range these are replaced re spectively by condensers 26 and 26a. The oscillator circuit which is of the Colpitts type is tuned by the condensers 27, 28 in one range which for the second range have connected across them, by means of a switch 37, condensers 35 and 36. Tracking at the extremities of the range is ensured by making the coil 6 of slightly greater diameter than coil 5. Tracking at a middle point is attained by connecting a condenser 33 across a portion of coil 6 while for the other range a second capacity 43 is connected across 33 by a switch 42 ganged with switch 37. An additional inductance 44 is connected in series with condenser 35.

Abstract: Disposable diapers having elasticized waistbands which allow the diapers to breathe and which reduce the incidence of waistband rollover. The waistbands are formed by affixing elastic elements between the topsheets and the backsheets (in the waistband region of the diapers) using regularly spaced, transversely extending regions of securement. Regions of nonsecurement are formed between pairs of the regions of securement thereby forming channels which allow the diaper to breathe and also forming corrugations which tend to inhibit waistband rollover.

Abstract: 931,049. A.C. motors. CONSOLIDATED ELECTRONICS INDUSTRIES CORPORATION. Jan. 2, 1962 [April 14, 1961; May 10, 1961], No. 102/62. Class 35. A self-starting electric motor comprising at least one ring of salient stator poles, and a permanent magnet rotor having pairs of poles, adjacent rotor poles being of opposite polarity, is characterized in that the rotor always assumes a position, when the stator is in a deenergized condition, in which each stator pole is substantially equidistant from the adjacent pair of rotor poles. As described, Figs. 1, 2, a synchronous motor has stator poles 25, all of which are energized with a similar polarity by coil 12, mounted inside a housing which comprises an end plate 10 and a cover 11. In modifications, Figs. 6, 7 (not shown), the stator poles are formed by bending up segments of the cover and end plate respectively. The rotor 21 comprises an annulus of a barium ferrite, magnetized radially to give alternate north and south poles, mounted on an aluminium hub 22 by, for example, cementing or die casting. An epoxy or other thermo-setting or thermoplastic resin may be employed as a suitable bonding material 24. With the arrangement described, the rest position of minimum reluctance is as shown in Fig. 3, with each stator pole equidistant from a pair of rotor poles, thus ensuring self starting. Known methods may be used to ensure that the motor runs only in one direction, e.g. a friction-operated pawl.

Title: Improvements in and relating to differential drive mechanism
IPC: F16D41/00
Filed: 1922-01-03
Abstract: 195,179. Harris, W. H. Jan. 3,1922. Differential gearing comprises two one-way clutches side by side, each clutch comprising a pivoted dog 46 put into action by the yielding of a transmission member 40. Each member 40 comprises a central boss and two pairs of long fingers 41 and two pairs of short fingers 42. The fingers 41 project into register with slots 44 in a main driving casing 28. The fingers 42 are in the planes of the dogs 46 which latter are carried by loose plates 39. The differentially driven members 33 have internally toothed rings 37 in the planes of the dogs. When resistance occurs in either clutch, fingers 41 yield so that the coupled fingers 42 rock the dog 46 corresponding into locking engagement with its ring 37. When resistance ceases, the fingers 41 straighten and the dog 46 is rocked to a free position so as to allow over-running.
